Not mingling indoors does not preclude pubs, socialising or hanging out with people in person.
I see from your comment history that you really enjoyed the commutes, going to an office job with others in the s/w industry. I'm like you in that regard: I was excited to start a job commuting into London on a daily train, because I really enjoy that part, the travel, the people, the vibe of the crowds. It's an excellent time to break out a book. I'd spent too long doing WFH and wanted a job in an office.
But things changed. You don't know my circumstances, but suffice to say my family faced a realistically high chance of death or disability if they got Covid due to particular pre-existing conditions. So of course I'd be a selfish arsehole if I carried on a commute in those circumstances.
